Occultation event with (54656) 00SX362, event index number 4578
Regions able to see the event: SAmericaS
Geocentric closest approach at 2026/11/06 07:40:54 UTC
J2000 position of star is 06:27:20.3 +01:59:10
Equinox of date position of star is 06:28:44.1 +01:58:05
Star is 91 degrees from the moon. Moon is 9% illuminated.
Stellar brightness G=13.8, apparent brightess of occulting body is G=16.3
Use an exposure time of 0.20 seconds with the standard RECON-QHY system.
SNR of 9.2 per integration for unocculted signal
Expected flux drop is 91% with SNR of 8.4 for the occulted depth (per occulted point)
Apparent velocity is 8.2 km/sec on the sky relative to the star, or, 8.1 arcsec/hr.
Position angle of asteroid motion is 74.9 degrees
The recommended exposure time corresponds to 1.6 km per image.
The 1-sigma error in the time of the event is 2.9 seconds.
The 1-sigma cross-track error in the shadow position is 25.6 km.
The sky-plane scale is 3632.9 km/arcsec.
Diameter estimates:
44.9 km assuming a 5% albedo, maximum of 5.5 sec for a central chord
18.3 km assuming a 30% albedo, maximum of 2.2 sec for a central chord
Cross-track diameter of 37.7 km used for deployment plan.
